Additionally, dose anyone know the safe maximum operating temperature for this CPU?
Run a program like CoreTemp, which shows the maximum CPU junction temperature Tj max. This value can be different for each type of CPU. Itried CPUID HWMonitor, and it shows CPU core temperatures, but does not give the Tj max value.
The E5 CPUs are designed to run at high temperatures for maximum performance. To put is briefly, the limit of performance is determined by the CPU die maximum temperature Tj max. The higher the frequency, and the more the cores are used, the higher the temperatures. I have run many systems, for months at a time, at 100% CPU usage, and the CPU core temps were up to 10 deg. C. below Tj max, using the HP CPU heatsinks. (Note: if one removes the CPU heatsink, always use fresh thermal paste, otherwise CPU temps will be hotter than they should be)
If the CPU has a Tj max of 91C, for example, it is OK to run the the CPU at 80C for extended periods. Intel throttles CPU speeds if they get too hot. Increasing the CPU fan speed manually can reduce temperatures, but the fans will be noisier. Some users like to have quieter systems, so it is normal to see "high" cpu temps, but a "high" CPU temp number by itself does not mean much without knowing the Tj max. (Note: Tj max is different than Tcase)
